To all whom t may concern.'

Be it known that I, FRANKLIN B. GIEsLEn, a citizen of the United States, and residentof Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented eertain new and useful Improvements in Apparatus for Treating Grain and other Materials; and I do hereby declare that the following is a full, clear, and exact descrip tion thereof.

My invention consists in what is herein particularly set forth with reference to the accompanying drawings and pointed out in the claims of this specication, its object being to provide simple, economical and eihcient apparatus of the rotary pneumatic drum type for the treatment of grain and other material to malt or dry the same.

Figure 1 of the drawings represents a central longitudinal section view of a rotary pneumatic malting drum type of graintreating apparatus in accordance with my invention, parts of the same being broken away; Fig. 2, a transverse section View of the same indicated by line 2 2 in Fig. 1; Fig. 3, a view similar to saidFig. 1, illustrating the drum organized for attemperating and drying the material under treatment, and Figs. 4 and 5 transverse section views respectively indicated by lines 4-4 and 5-5 in Fig. 8.

Referring by numerals to the drawings, 6 indicates an outer non-perforated shell portion of a rotary pneumatic drum and 7 each of a pair of flanged end rings to which said shell is suitably secured. The flanges of the ring are provided with hand-holes at suit able intervals apart, and covers 8 for these holes are bolted to said flanges. Extending inward from each of the rings 7, at regular intervals apart, is a series of radial webs 9, and in lish-joint connection with these webs are registering webs 10 that radiate from the hub 11 of a spidenplate 12 having an annularly flanged and countersunk open portion 13, concentric with said hub, and the perimeter of said plate has lap-joint match-fit upon the flange 7 of the adjacent end-ring totherewith form a head of the aforesaid shell. Bolted to the ring-webs 9 are channel-irons 14 to which plates that go to make up an inner perforated shell 15 of the drum are riveted or otherwise suitably secured, and braces 16 for said shell are likewise fastened to the end rings of the drum. The shell 15 and non-perforated heads 17 of the same are connected by angle-iron rings 18 to which they are suitably fastened, and angle-iron stays 19 are likewise attached to said heads and the webs of the end rings and spider-plates of the drum. From the foregoing it will be understood that a series of longitudinal air spaces are provided at regularly recurring intervals between the two aforesaid shells of the drum, and that the spaces are in communication with a corresponding series of radial air-s aces between the heads of said shells. 'ingaging countersinks of the spider-plates 12 are iiared ends of arms 20 and 21 of airsupply and air-exhaust flues, exible gaskets 22 being provided in connection with said ends of the flue-arms to oppose the flanges 12 of said plates and thus provide air-tight joints between said flue-arms and the drum. butterfly check-valve 23 is preferably provided in the arm 2O of the air-inlet flue, and a perforated distributer-pipe 24 extending longitudinally of the drum, central of the same, is connected by a swivel-joint, in said {ine-arm, with a feed-pipe 25 for water or steam, the end of said distributer-pipe in the flue-arm 21 being capped or otherwise closed.

Fitting the hubs of the spider-plates 12 within the same, as in Fig. 1, or on the same as in Fig. 3, are hubs of stationary segmental valves 26 and 27, and suitably disposed rings 28 are employed to maintain the engagement of said hubs. The disposition of the valves 26 and 27 is such, that they close an equal amount of air space between the heads of the aforesaid shells, but in opposite direct-ions, the valve 2G at the air-intake end of the drum being for the most part above and the valve 27 for the most part below a line of 45o through the center of said drum, and hence above and below the Obliquity of the material under treatment in the drum, there being constant shift of said material incident to the rotation of said drum. To prevent the valves moving with the drum, they are provided with stops 29 in opposition to similar devices 30 provided in the arms 20 and 21 of the flues aforesaid, and as shown in Fig. 3, provision may be had for lubricating the hubs of the spider-plates 12, which hubs turn in or on those of said valves as may be preferable in practice.

The drum as thus far described may be utilized for treating grain or other material when provision for attemperating the same in said drum is unnecessary. The air admitted through the iiue-arm 2() finds its way down the open radial air-spaces between the heads of the shells 6, l5 of the drum into the communicating longitudinal spaces of the same, then up through the material in said shell 15 and out through other longitudinal air-spaces into radial air spaces that are open to the exhaust-flue arm 2l, moisture being supplied t-o said material, as may be necessary, through the distributer pipe aforesaid. The material being discharged from the drum, the latter may be cleaned and sterilized by water and steam discharged therein through the aforesaid distributer-pipe, suitable drain-outlets common in the art but not shown being provided.

As best shown in Fig. 3, a dished casting 30 may be bolted to the inner side of one head of the perforated shell of the drum to form a chamber connected by pipes 3l with a similar casting 32 made fast to an expansion and contraction plat-e 33 secured in connection with the inner side of the other head of said shell to form another chamber, the two chambers being in communication with the then hollow hubs l1 of the aforesaid spider-plates, and a section 24: of a water and steam distributer is connected to the castings 30, 32. A feed-pipe 35, for cold o-r hot water or steam is in swiveljoint connection with a nozzle 36 iitted to n the hub of the spider-plate at the air-intake end of the drum, and a sect-ion 24 of the distributer pipe extends through said joint to have similar joint connection with a feedpipe 25. An out-let nozzle 37 iitted to the hollow hub of the spider plate at the eX- haust-end of the drum has swivel-joint connection, in the flue-arm 21, with a wastewater pipe 38. Cold or hot water is run through the circulating system above speci- Y fied to attemperate material under treatment in the drum, and steam run through the same system will serve to create a drying heat in said drum that rotates in the direction of the arrows in Figs. 2, 4 and 5.

The drum is cradled and driven by mechanism not shown, but common in the art of rotary pneumatic malting drmns and rotary steam driers.
